问题描述

我有以下问题:

我是JSF2和Primeface的新手.

I'm new to JSF2 and primefaces.

在用户输入字符串并单击CommandButton之后,页面上有一个表,该表中将填充信息.单击按钮后,我希望在处理结束之前将其禁用.

I have a table in a page that will be populated with information, after the user enters a string and clicks a CommandButton. After clicking the button, I want it to be disabled until processing is over.

要禁用CommandButton,我需要执行以下操作;

To disable the CommandButton I'm doing the following;

<p:commandButton update=":outPanel" widgetVar="btnSend" id="btnsend"
     value="Calcular" actionListener="#{calcBean.getTrfs}" 
     onclick="btnSend.disable()" oncomplete="btnSend.enable()" />  

然后有一个面板,我想在其中显示其内容:

And then I have a panel where I want to show its contents:

<p:panel id="outPanel" widgetVar="outpanel">
         #{calcBean.result}
</p:panel>

首次加载页面时,如何隐藏此面板?

How can I hide this outpanel when the page loads the first time?

单击CommandButton时如何隐藏它,并且仅在bean中的处理成功后才再次显示它?

How can I hide it when I click the CommandButton, and only show it again if the processing in my bean is successful?

谢谢.
